OPERATING PRECAUTIONS
Installing pump
The fire pump must be installed on level ground. Otherwise, an
accident may occur.
If the fire pump should be installed on uneven ground, it must
be secured.
Place the pump as near as possible to water source, and water
suction height as low as possible.
When putting the portable fire pump down to the ground, put it gently
and horizontally.
In case of the inclined location or uneven ground, make sure that the
water suction hose is lower than the suction port of the pump.
In case of the suction hose is put undulated, air can be left easily in
the hose, and possibly cause suction inability when the water
discharge valve is opened.
In case of the suction inability due to air remaining in the suction
hose, set the water discharge valve half-opened, and operate
vacuum pump until water is discharged continuously. (for 3 to 5
seconds from beginning of water discharge)
Be sure to install strainer and basket on the end of suction hose. If
the pump may suck sand or mud of the bottom of water source,
place sheet below the basket.
Strainer and basket of suction hose should be placed more than 300
mm (11.8 in) below water surface to prevent suck of air.
Discharge hose should be arranged not to be bent.
